VMware Edge Gateway VPN to Cisco ASA

KB ID 0001658 Problem I was asked to setup a VPN to help out a colleague this week.

Get Ready for LDAPS Channel Binding

KB ID 0001645 Problem I have written about Enabling LDAPS a long time ago, but it’s a subject that’s about to become important again, so I’ll revisit the subject. Microsoft are about to ‘enforce’ LDAPS authentication against their domain controllers, in the March 2020 round of updates. Now delayed until second half of 2020. What does that mean?
